To all wwm if may concern:

Be it known that we, Jouw' Gomimiioicii anni Kuoni/WAGNER, citizens ofthe United Sintes, residing, iespeciiveiy, at Youngstoiizi, eoimtyoiMahoning, sind Stato of iiio, and iiiiicinnaii, county of Hamilton,Stato of Ohio, have invented, @,eitziin new anni useful 'improvements inRendering and Drying Hants, of which the ifoiiowing is a Specification,

This invention reiates to the subject of refining', rendering, steaming,drying, and oon- Vsiiious products, and psticuiariy to a. piumaembodying improved msiumentaie ties foi rsfining, isndozing, anddrying', in mpifi and. effective mamies, igsiiow, guesses, ami fats fiomanimal of Vegetable inst-tei, go "ooge, and nigii soii.

To provide for the introduction of material. into the tank, the dome ais provided with a top receiving man-hole 11, surrounded by anupstanding ilange 12, about which are arranged a plurality of sets ofhinge lugs 13, which provide for the shiitable mounting of the swingingcover 14. rllhc said cover is adapted to snugly rit on the man-holeflange 12 and is equi pcd with a carrying bar 14lL .having pivotamounting intermediate its ends, as at 15, on top of the cover, andarranged to have one end hinged, by means of a detachable hinge-pin 16,between a pair of any of the sets or hinge-lugs 13. Hence, by reason ofthus arranging the carrying member for the cover 14. the latter may bemounted to swing open in any of several directions as may be mostconvenient, according to the set-up position or location of the tank.Those hinge-lugs 13 which are not utilized for the hinge mounting of thecover have `fitted thereto the ordinary type of swin or hinge bolts 17,adapted to havea releasale clamping engagement with the biturcated clampears 18, projected from the edge of the cover in a spaced relationcorresponding to the spacing of the sets of hingeugs 13.

The removal of the solids from the bottom of the tank is effected throuh a bottom discharging man-hole 1.9 formed wall of the tank immediatelyabove the plane of the bottom 8 thereof. This. discharging man-hole orman-.hole iitting 19 is e uipped with Aa door or cover 20 mounted and camped in. position in any approved manner.

'The main heating jacket 3 is supplied with heat by means of a main heatsupply pipe 21, in communication with the jacket 3, and designed toreceive and carry a supply of steam or hot air. The latter, entering thejacket 3, fills the same throughout and thereby provides a heated wallfor the tank, and in addition to tuus applying heat external y to the fsolids and liquids within the tank, the steam 'hot air into the chamber10.

in the jacketed'* seared or hot air is delivered directly into suchcontents from the surroundin wall ci" the tank through the medium of a purality of heat circulating pipes 22. These are arranged upon theexterior of the tank and communicate rcspectively with the jacket 3 at23, and with t 1e interior of the tank at 24 as maybe plainly seen fromFig. 2 of the drawing. The said pipes 22 are equipped with suitablenon-rcturn check valves 25 to prevent the outward escape of the contentsJfrom thc tank, and are also Jfitted with suitable cut-oil. valves lliwhich may be opened or closed at will as ronditions require.

Supplementing the pipes the apparatus is further equipped. with a bottomhoatcir culating pipe 27, which respectively connects with the jacket 3aspat 28, and with the intorior of the bottom heating chamber 1() as at29, to rovide for circulating the steam or The latter also acts in thecapacity of a drain chamber from which drain water may be drained oll'lthrough a drain pipe 30. In case of the use of steam, thejsteam anddrain water passes through the pipe to a steam trap 3l of any approvedconstruction and performing the usual functions, and in this connection,Ait will be observed that the main drain pipe 3() Ihas connectedtherewith a branch drain pipe 30@ vhaving communication with the heatingjacket 3 at the bottom thereof, as plainly indicated by the dotted linesin Fig. 2 ol' the drawings. This branch drain pipe connection 30a'subserves the same function with the jacket 3 as the main drainA pipe 30subserves in. connection with the'bott'm heating chamber 10.

The system of pipe connections is comleted by the employment of the heatcircuating pipes 32 and 33 which serve to supply steam or hot air fromthe heating jacket 3 to the interior of the tank T, respectively in theplane of the upper and lower revolving agiv'tators 34 and 35 .to bepresently referred to.

Each of the pi es 32 and 33 is equipped with a non-return c eck valve 36and wlth a controlling or cut-off valve 37 which may be opened andclosed at will to suit the condit1ons of the process. The pipe 32 has aconnection at one end as at 38 with the heating jacket 3 of the tank,and at its other end as at 39 with the interior chamber of the tank vinthe plane of the upper revolving agitator posite ends respectively withthe heating jacket 3 as at 40, and with the interior of the tank as at41, the latter point being in the plane of rotation of the loweragitator so as to admit steam or hot air into that portion of thecontents of thc tank whicl'i is bcthe converting tank.

'In other Words, the lay-pass 93 ridges the valves 94 and 95 and isintended to be used in the rendering or cooking process, Whereas, Whenthe apparatus is used for drying, the by-pass 93 will be closed andcommunication opened direct throu valves in the main pipe 4.3, 'as thereWi l then be greater' pressure 1n the tank. The bypass 93 is required toprovide a similar escapeV port While rendering.
